Multiple-Reflection Cell Structure Simplification
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing multiple-reflection cells have complex structures and large internal volumes due to the need for multiple mirrors to achieve both long and short optical paths, making them inefficient for measuring components with high and low concentrations simultaneously.
Innovation Solution
The analysis device employs a multiple-reflection cell with a pair of reflecting mirrors that allow first and second lights with different incident optical paths to enter and exit, simplifying the structure and allowing simultaneous measurement of high and low concentration components by varying the number of reflections and using a common optical window for both lights.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple mirrors are used to achieve both long and short optical paths, then measurement range is improved, but device complexity increases
Solution Approach 1:
The patent applies universality by making a single optical path configuration serve multiple measurement functions. By adjusting the number of reflections in the multiple-reflection cell, the same optical path can measure both high concentration components (fewer reflections) and low concentration components (more reflections), eliminating the need for separate long and short optical path configurations.
2Adaptability or versatility
If multiple mirrors are used to achieve both long and short optical paths, then measurement range is improved, but internal volume increases
Solution Approach 1:
The patent applies parameter changes by varying the number of reflections rather than changing the physical configuration. By keeping the optical path geometry fixed and only changing the reflection count parameter, the system achieves different effective path lengths for measuring different concentration levels, avoiding the need for multiple mirrors and large internal volume.

AI summary
The present claimed invention makes it possible to simplify a structure of a multiple-reflection cell and to measure both a measuring objective component having a high concentration and a measuring objective component having a low concentration. The analysis device 100 of this invention is to irradiate a light to a multiple-reflection cell 20 into which a sample is introduced, to detect the light exiting from the multiple-reflection cell 20 and to analyze a measuring objective component contained in the sample, and comprises a first light irradiation part 10A that allows a first light L1 to enter the multiple-reflection cell 20 and a second light irradiation part 10B that allows a second light L2 to enter the multiple-reflection cell 20. The multiple-reflection cell 20 has a pair of reflecting mirrors 22, 23 that reflect the first light L1 and the second light L2.
